Momentary Small Lean Spike at VTEC Point

[atlex]

Hi Folks,

I've got a small lean spike in WOT when I hit the VTEC point.

It's small but it's annoying me in an OCD sense. I'm not seeing a loss of performance but no matter what I've tried, I can't seem to tune it out.

The map is giving sensible WOT AFRs between 13.1 and 12.7 (I've aimed for about 13.0)

<VTEC>
It goes 12.6 13.6 12.8

I want to know, is there any way to tune it out, or should I just ignore it ?

Car is a swapped MR2 Spyder with CAI/Cone Filter & 4-2-1 Header. Stock internals EP3 K20A2. WB is an AEM-X.

Datalog, Map and Photo of the Graph attached.

Thanks!

Also if anyone's bored and wants to review my map, I'd appreciate that. It's a road tuned map I've prepared for pleasure/experience before I swap to an RRC intake manifold and spend money on dyno time. 50 degree cam at 4500 because it sounds so good.

Don't worry about it, that is normal when the cam changes from low to high.

Thank you, that's good to know ^^

As for the fuel tip in - have I been aggressive enough ? I don't get bog. I'm not sure how much transient leans matter.
